program to support MPI<tt>s name publishing features with hydra 
<H2>Description</H2>
Hydra is the default name service for MPI\</tt>s name publishing features
(MPI_PUBLISH_NAME/MPI_LOOKUP_NAME). For programs launched by separate
hydra instances, a separate nameserver mechanism need be launched in
order for the name publishing to work across multiple process managers.
<P>
This can be achieved with hydra_nameserver. For example:
<PRE>
    shell@myhost1$ hydra_nameserver &amp;
    shell@myhost1$ mpiexec -hosts myhost1,myhost2 -n 4 -nameserver myhost1 ./a.out
</PRE>
